Abstract
Multihop Wireless Broadcast is an important factor in VANET. Broadcasting is the most common operation which is used by many applications. But efficiency in routing is difficult to achieve. Many other protocols consider the performance degradation based on the factors like Node density, spatial distribution pattern and channel quality. Distribution Adaptive Distance with Channel Quality (DADCQ) protocol overcomes these factors considering all the three factors. The protocol utilizes the distance method to select forwarding nodes and also the results to achieve high reachability and low bandwidth consumption in urban and highway scenarios. But there is no guaranteed packet transmission and selecting threshold value by considering all the difficult factors. This can be achieved by using Position Based Routing Protocol by put into action of GPRS Algorithm. The PBR protocol makes use of location information and suited for distributed, centralized and decentralized systems. Thus the proposed system will considerably reduce packet loss and to improve throughput.
